What comes in the kit and how does it help during installation?

This kit ships with one oil cooler line plus two gaskets so you won’t need to source seals separately during installation. Including gaskets reduces the risk of leaks and helps achieve a proper seal at each connection point.

• Contents: 1 x oil cooler lower pipe (15767-31020) and 2 x gaskets (11496-31010, 15785-0P010).
• Gaskets included to prevent immediate fluid loss and ensure factory-like sealing.
• If gaskets are missing, NOVAPARTS customer service offers replacements within the 365-day support window.
• Pre-check part numbers and visual comparison recommended before removal.

How durable and reliable is this replacement line compared to OEM?

NOVAPARTS supplies aftermarket parts built to meet or closely match original equipment specifications for fit and function. Materials and connection points are engineered for routine engine oil pressures and temperature cycling typical in these vehicles.

• Constructed for longevity under engine oil flow and thermal stress.
• Manufactured to align with factory mounting points and hose fittings.
• Sold with a 365-day service support policy for replacement or refund.
• Suitable for professional or experienced DIY installation; inspect for corrosion or damage before reuse.

What should I know about installation and maintenance?

Installation requires basic mechanical skills and common shop tools; be prepared to drain oil and handle fluid safely. Replacing the cooler line is an opportunity to inspect surrounding hoses, fittings, and the oil cooler for wear.

• Drain engine oil as needed and clean mating surfaces before fitting new gaskets.
• Tighten fittings to manufacturer torque specs to avoid over-compression of gaskets.
• Check for leaks after warm-up and road test; re-torque if recommended by service manual.
• Keep the removed part number handy to verify compatibility when ordering replacements.

Who is this for: This NOVAPARTS oil cooler line and gasket kit is aimed at vehicle owners, independent mechanics, and repair shops working on Lexus RX350, RX450h or Toyota Highlander, Sienna and Venza models within the listed years who need a direct-fit, cost-effective replacement. It’s appropriate for those who prefer a ready-to-install assembly with included seals and backed by seller support for part verification and after-sales assistance.
